Yes, it would seem so. Not an expert but my guess is the earliest use of diacritics appeared around 100 years after Mohammad's death. So even, being generous the claims they make in the article don't hold water.
The probability is fairly high that this is a very old piece of animal skin with some Quranic text written about 100 years or so after his death (being generous).

We have piles and piles of contemporary historical evidence in multiple forms (statues, tablets, pottery, artwork, etc.) for many important and lesser important persons in history both much more ancient and equally ancient, but for him, nothing. It is only after a significant time gap after his death that we find a trickle of evidence and then a torrent. Exact same thing for Jesus.

How these things develop can be easily seen on the more recent and good documented example of
